zo claim. (ci. assess) This invention relates to tabulating and listingmachines of the type adapted to.. select from a large number ofdata-carrying cards or slugs certain ones conforming to any. desiredstandard.

Broaldly, the object of the invention is a combination addressing (orlisting), tabulating and counting machine, wherein all indicia of theslugs or record members are available to determine selection orrejection, and wherein the selection or rejection of slugs or'recordmembers is determined by a matrix member which may'also determine thedisposition of the particular slugor record member as regards listingor.printing information from said record member or for accumulating inan adding register numbers indifcated by indicia in said slug or recordmember, sorting not being necessary to secure information.

More specifically, it is an object of our invention to provide anaddressing or listing machine bearing elements or slugs and tabulatedata from either the selected slugs, rejected slugs, or all Anotherfeature is the provision of atabulating listing machine having means forselecting slugs, and counting means for recording the number ofrejected,.accepted, and total slugs, and means for preventing countingwhen no slug is fed.

A'further feature is the. provision of a machine which is adapted tosort out different slugs having common characteristics, from a largenumber of slugs, the sorting operation being Another feature is theconstruction of a tabuadapted to perform a large number of difl'erentoperations depending on certain guiding indicia carried by aninterchangeable controlling member or matrix.

A further feature of our inventionis the incoro poration in a tabulatinglisting machine of 'a plural feed or differential accumulator whichaccumulates digits from numerical data, 'into all orders and carriesover from one order to another simultaneously.

A still further feature ,is the provision of a tabulating listingmachine comprising `a plurality of units,

all of which may be made identical and separate unit.

selections and tabulations made at each ofthe next unit.

Another object is the provision of a listing machine indicia-bearingmember, or slug, having a number of numerical data recording positions,each position having a plurality of indicia.

In accordance with our invention, a. tabulating 5v listing machine isconstructed in the form of a plurality of identical or similar unitswhich may be adapted to bereadily interlocked in any desired series sothat a common driving mechanism serves for the entire group, the driveshaft of one l0 unit being detachably coupled to the drive shaft l Inaddition to the tabulating and listing a power drive and slug or cardfeeding unit, and also-one or more slug receiving magazine units areprovided. l'I'he slugs or cards 15 are fed from the slug feeding unit tothe ltabulating and listing units successively so that each unit acts ata different time on each of the slugs. The units may be provided withprinting mechanisms and leach may be adjusted to list and record 20different characteristics of the same slug or card or characteristics ofdifferent slugs or cards.

In addition the magazine unit or umts may be adjusted so as to separatetheslugs intotwo or more groups, according to the indicia borne by 25each slug.

In the preceding and following description the words indicia bearingelement or slugs are intended to embrace in general any element carryin!indicia of any form whereby information 30 may be obtained. The elementsmay be made of thin metal, cardboard, or any sheet material marked byembossing, perforating or attaching identifying tabs or rivets. Likewisethe slugs may be made of cast material provided with identifyingcharacteristics in any suitable manner.

The words matrix and standard are used generally to designate any devicerepresenting definite preselected indicia corresponding to a certain setof conditions or presenting certain inr formation. The matrix orstandard may be made of sheet material such as metal or cardboard,suitably perforated, embossed or provided with identifying tabs, rivetsor other suitable means.

If desirable the matrix may be made of cast ma- 45 terial suitablymarked.

In the following description when I speak of comparing a slug with amatrix, or reading the slug I mean the step of comparing a slug with amatrix to determine whether some or all of the embcsslngs, perforations;or added indicating marks carried by the slug are similar to theperforations, or `other identifying indicia of the matrix.

Each unit comprises means for feeding a slug to a plurality of differentpositions, and means at the different positions for performing differentactions upon the slugs. At the first position, the indicia on each slugare compared with a matrix or standard on which has been indicated thecharacteristics vdesired or not desired. Associated with the comparingor reading mechanism is means for determining the future action whichmay be taken with respect to the slug. For example, the data on the slugmay be printed on a sheet of paper at a subsequent position. Likewise,means is associated with the reading mechanism for tabulating anydesired numerical data indicated on the slugs. The matrix or standard isarranged to control the tabulating mechanism so that any part or all ofthe numerical data may be tabulated, different accumulating mechanismbeing provided for the individual parts thereof. In order to insure thatfalse tabulation will not result when the indicating members or slugsare not being fed, blocking means is furnished for preventing bothprinting and tabulating when no slug is fed. Means is also provided forcounting the total number of slugs fed as well u the rejected oraccepted slugs.

Where it is desired to sort into a group slugs having certainpredetermined characteristics a magazine unit may be adjusted to selectthe desired slugs and reject the rest.

For the tabulating of the numerical data carried by the slugs, adifferential or plural feed accumulator is used. This accumulator isadapted to carry digits into all orders at the same time andsimultaneously carry over from one order to the next whenever necessary.We have also arranged our mechanism so that one long accumulator may beused and be divided into a plurality of recording groups so that acertain number of indicating positions will record one series of resultsand another number of positions will record another series of results.'Ihis arrangement is particularly useful where the data carried by thecards may be of widely different characteristics, for example, one groupmay require a maximum number of five digits corresponding to a numberrunning to tens of thousands whereas other data may require but 3`digitstherefore, running only to hundreds. The machine may likewise be used onslugs which have the data arranged differently altogether, for example,it may be arranged to form one group of figures running to totals of theorder of millions in which case the entire length of the accumulatormight be used. We have also arranged the actuating mechanism for theaccumulator so that the data contained on one portion of a slug may befed into any portion of one accumulator or into any one of severalaccumulators, as desired.

Reading of the indicia on the slugs is preferably accomplished by agroup of feeling fingers, which are thrust into engagement with the slugto set up an indication, and then instantly lifted free from the slug soas to permit the advancement thereof to a succeeding position.

Broadly the entire invention comprises a machine each unit of which isadapted to choose desired from undesired slugs, and printand/or tabulatepredetermined data from selected or rejected slugs, both or neither, orsort the slugs into groups, all these functions being controlledindependently for each unit of the machine by a prefashioned matrix.

The machine maybe put to many different uses depending on the kind ofbusiness in which it is used and data on which information is desired.The indicating members or slugs used in the machine may be made eitherof sheet metal, cardboard, or other material provided with embossedprojections, perforations or other suitable indications as heretoforestated, the position ofwhich indicates data carried by the slug. Theslugs may likewise be made of cast metal with the projections integraltherewith. Or the projections may be of the form of pins or rivets addedto a slug. Any information which it is desired to print from the cardmay be incorporated in the slug in raised symbols like type or cut outto form a stencil. When it is desired to file or record data regardingcertain persons or transactions, it is merely necessary to impress uponor attach to the slug projections in the correct positions or perforatethe slug in a corresponding manner. While the slugs may be of any typeand arranged to have any number of positions and characteristics, I findit advantageous to utilize 2i rows of projections indicating certaingroup characteristics, each row being capable of carrying projections,or more normally one projection in any one of ten different places inthe row. The particular location of the projections in each row servesto indicate the detail characteristic of that particular maincharacteristic indicated by the position. When it is desired to select agroup of slugs carrying certain information, itis merely necessary toarrange a proper matrix which is provided with perforations or otheridentifying characteristics corresponding to the different desireddetail characteristics of the slugs. This matrix is inserted in one ofthe units and the various slugs run through the machine thereby causingthe desired information either to be tabulated or printed, or both, bythat unit. At the same time a record may be kept of the total number ofaccepted slugs, rejected slugs, and oi both lots.

The above mentioned and further objects and advantages and the manner ofattaining them will be made clear in the following description andaccompanying drawings.

Fig. 20 is a sectional view in end elevation taken alongline 20-20 ofFig. l showing the slug sorting mechanism.

Referring more particularly to the drawings, Fig. l shows a listing,tabulating machine constructed in accordance with our invention, andcomprising a power unit 1, a series of tabulating listing units 2, 3 and4 and slug sorting or receiving magazine units 5 and 6. Slugs are fedfrom a magazine 'I in unit 1 along a. conveyor 8 through the severalunits, wherein the slugs are acted upon in the desired manner, andfinally some or all of them stored in a receiving magazine 9. Power fordriving the'entire working mechanism is derived from an electrical motor10 which is enclosed in the power unit l, and a series of driving gears1i of part of the accualong line 16-16 .of

units. Associated with` the drive shaft of the motor 10 is a clutch 12which is of any well known type adapted for stopping thegears 11 in a.certain predetermined position every timeA the clutch is released. Foroperating the clutch a control lever 13 is utilized. `When it is desiredto stop the progression of slugs through the various units, the lever 13is turned. whereupon the motor l0 isfreed from the gears 1i by means ofthe clutch 12. Because of vthe particular construction of the fclutch,the gears always vstop at exactly the same position, and therefore leavethe slugsin the machine at exactly the same pointeach time the machineis stopped. s After having passed through all of the preceding units theslugs may be stored in either of the receiving magazines 9 or 9'. Thismay be accomplished in any desired manner, for example, in magazine 9 bypusher plate 14 which thrusts towards and away from the magazine 9 bymeans of a suitable linkage 15 driven from a power shaft 16. Each timethe pusher plate moves towards the magazine it forces downwardly a slugwhich has been fed on top of the magazine. The slugs under pressure fromthe pusher plate may, for example, cause a frictionally held bottom inthe magazine to move sutilciently to accommodate lthe slugs successivelythrust therein. The magazine 9 may be controlled by a matrix either tocollect all slugs or only those having certain predeterminedcharacteristics. The manner in which this is brought about is explainedmore fully hereinafter.

Theunits 2, 3 and 4 may be all identical, each which serve to actuatethe power- -a carriage 42 and are one comprising a pair of side plates17 and 18 held together by suitable tie rods 19, 20, 21 and 22. (Figs. 2and 4). For supplying the power necessary to operate the mechanism ofeach unit, a drive shaft 23 is provided. This shaft has at each endsuitable coupling means 24 so that when two. units are bolted together,or when one unit is secured to the power unit, the two shafts will bemechanically interlocked through the agency of the couplings carriedthereby. As shown in Fig. 7, the coupling may comprise a key portion orfeather 25 secured to the end of the shaft 23 and adapted to engage aslot or keyway 26 in the corresponding shaft of another unit. As all ofthe units are the same, each shaft 23 will have at one end a key 25 andat the other end a keyway 26. 'Iwo adjacent units may be clampedtogether by means of bolts 27, which pass through the walls of theplates 17 and 18. The entire working mechanism is enclosed by a suitablehousing 28 which may be of sheet metal or other material.

Slugs are fed one at a time from the magazine 'l in which they arestacked vertically, by a conveyor 8. This conveyor is reciprocated bymeans of a gear 29 forming part of the gear train l1 and havingconnected thereto a connecting rod 30, the other end of which is securedto the conveyor. (See Fig. l). f

The construction of the conveyor will be more clearly understood byreference to Figs. 3, 1l and As shown in these figures, it comprises aslidable channel member 31 carried in a guide trough 32. Pivotallymounted within the charinel member is a series of pushing pawls 33 whichare pivoted to 31 at 34. Each pawl has a tail 35 which is held againstthe bottom of the channel member by means of a spring 36. The spring issufllciently resilient so that when the conveyor is reciprocatedbackwardly to get another slug from the magazine, the pawls 33 will bemoved down into the channel 31 thereby sliding underneath the slugs inthe conveyor trackway during .the return motion. After clearing theVrearend of each'slug, the pawls 33 snap upwardly, and upon advancemotion of the conveyor, serve to carry the slugs forwardly tojtheirnewpositions. For guiding the slugs throughthe v arious units, a traclrwayl3'1 is furnished.. (Fig. Si.) lThe trackway vis so constructed as tosubject the slugs to a frictional reta'ir'ding force during theirpassage therethrough. may be accomplished by having on the trackw'aylresilient hold-down plates 38 which pressthe slug against the track.

The conveyor 8 is made separable inl a suitable fashion so that theunits may be detached one from the other. The pivotal point 34 may serve'as a separation 4point for the conveyor as well as for supporting thepawl 33 (Figs. 11 and 12).

Each unit has two operating positions, as shown most clearly in Fig. 4.One of these is the reading position 39 and the other the printingposition 40. The throw of the connecting rod 30 is just enoughto advancea slug from one of these positions to the next, and the width oftheunits is just great enough so that a slug in advancing from theprinting position of one unit to thel reading position of the next unit,passes through one idle position.

At the reading position 39, a plurality of reading fingers 41 areprovided. (See Figs. 2, 3, 4, 7 and 8.) These fingers are slidablypositioned in held against displacement Cil by means of frictionretarding springs 43 which are secured to a suitable holding member 44fastened to the carriage 42. (Fig. 7.) 'I'he carriage in turn issupported by two pairs of pins and 46 sliding in grooves 47 and 48 in across frame member 49 (Figs. 7 and 8) attached to the side plates 17 and18, and the carriage is reciprocated by a lever arm 50 (Figs. 2 and3)which is pivotally supported on a rod 51 extending between the two sideplates 17 and 18. The upper end of the arm is pivotally secured to aU-shaped projection 52 on the carriage 42 by means of a pin 53. Theholes through which the pin passes in the U-shaped member are madeslightly elliptical so that rotary motion of the lever arm may betranslated into rectilinear motion of the carriage traveling in itsgrooves. The arm 50 carries a retracted position and position. As thecarriage is advanced by the cam 55, pins 46 are forced downwardly towardthe rod 51 by means of a cam surface 56 (Figs. 2 and 3) on the face of amember 57 slidably arranged in the member 49 and held in a forwardposition by a spring 58. This movement forces all of the feelers orngers 41 down to the level of the top of the slug 59, which is in aready position. As the carriage continues to advance towards the left,the fingers 41 encounter the embossed projections 60 on the slug 59 andarestopped thereby. Each feeler upon encountering a projection instantlystops, and while the carriage continues to -move forward, remains in` astationary position.

This action is permitted because the feelers are held only frictionallywith respect to the carriage 42, by spring fingers 43 and hence ifretarded sufficiently stand still and remain in which ever position theymay be stopped. 'Ihe carriage advances fully to the left position asshown in Fig. 3; then the pin 46 reaches the end of the memthe carriage42 immediately to rise to the position shown in Fig. 3, under thevinnuence of spring 61, thereby freeing the feelers 41 from the slug 59and permitting the slugs to be advanced another step by the conveyor 8.While the feelers are held in their forward position by the dwell in thecam 55, matrix 62 carried in a holder arm 63 rockably secured to theframe of the machine at 64,-is-moved into engagement with a plurality ofindicator fingers 65, one of which is carried by veach of the feelers4l. The arm 63 is rocked so as to move the matrix, by a push rod 66which is normally urged to a downward position by means of a cam 67carried by the shaft 23, and is urged upwardly by a spring 69, attachedto a stationaryrod 69. The push rod is held in its proper operatingposition by means of a collar 68 (Fig. 7) which encircles the shaft 23.The collar has an elongated opening therein which permits the necessaryendwise motion of the rod. At the proper instant of time; that is, whenthe fingers 41 have assumed the position shown in Fig. 3; cam 67 permitsthe push rod 66 to rise under the influence of spring 69, therebythrusting the matrix into engagement with the ends of the indicatorfingers 65.

The matrix is provided with a plurality of holeI 70, as best shown inFig. 6, which are punched to correspond with a desired arrangement ofthe embossed projections 60 on the slug 59. If the arangement of theindicator fingers corresponds to an arrangement of `holes 70 in thematrix, the matrix will rise under the influence of the spring 69l tothe position shown in Fig. 3. After the push rod 66 has risen to elevatethe matrix, and during the dwell of cam 67, three feeling fingers 71,72, 73 and a feeling bail 74 are thrust into engagement with the edgesof the matrix. This is brought about by means of a push rod 75 having acam rider 76 which engages with a cam 77 carried by the shaft 23. Theend of the push rod 75 has a collar 78 arranged similarly to collar 68of the push rod 66 (see Fig. 7),

The rod 75 is moved toward the shaft 23 by means oi suitable springs 83,thereby rotating a pair of arms 80, pivotally supported by a shaft 81secured to the side plates of the machine. Interconnecting the two endsof the arms is a tie rod 82. This tie rod normally engages the edges ofthe bail 74, but by the action of the rod 75, is moved to the left, asviewed in Fig. 3, out of engagement with the edges of the bail,permitting the bail to rotate to the left under the infiuence of thesprings 83 and engage the right hand edge of the matrix 62. Rod 75 issecured to the arms 80 at 84 and at this same point an elongated orslotted pivotal connection is made to a pair of rocker arms 84 which arepivotally mounted on a shaft 85 secured to the frame of the machine at86 (Fig. 8). Rocker arms 84 carry at their other end a tie rod 87 whichnormally engages the edges of the feeling fingers 71, 72 and 73 therebymaintaining said fingers in a position out of engagement with thematrix. As the rod 75 moves to the left, permitting the bail to engagethe edge of the matrix, tie rod 87 is rotated in a right hand directionwith respect to the shaft thereby permitting the feeling fingers to movetoward the matrix in a right hand direction and contact with the edgethereof. Finger 71 has a notch' (Fig. 6) edge of the matrix 62, if themartix is in the lower or unelevated position (as distinguished fromthat .shown in Fig. 3). If the matrix is in the lower position, thefinger 71 moves first slightly, i. e. to the edge of the matrix whichenters the notch 88 thereby permitting further movement to the right; inmoving to the right the finger 71 pushes the rod 89 connected with anarm 90 secured to a hollow shaft 91. which in turn through suitablemechanism, actuates a reject counter 92 (Fig. 1). 'I'he counter 92serves to record the number of slugs which do not compare with thematrix. .When the matrix is in the upper position, as shown in Fig. 3,the finger 71 is unable to move to the right, being blocked by the edgeof the matrix, and hence no count is made on the reject mechanism.

When the matrix is in the upper position, iinger 72 is permitted to moveto the right in a clockwise direction, (best understood from Fig. 6),the edge of the matrix as shown having a notch 93 which cooperates witha notch 94 in the finger thereby permitting the finger to move into theedge of the matrix. As the finger moves in under the influence of'aspring 72 (Fig. 5), it draws a drag link 94 to the right, thereby movingthe lower end of a locking pawl or dog 95 in the same direction (seeFig. 3). This movement of the dog unlatches it from a pin 96 secured tothe end of a bellcrank 97 carrying at its other end a printing head 98.The dog 95 is held in the right hand position by leaf spring 99 whichwhich registers with the the bellcrank strikes 'This movement thrusts alto its initial position with the matrix in its upper position, thefeeling finger 73 moves to the right similarly to 71 (see Fig. 6), andpasses the edge of the matrix by virtue of a notch 102 in the finger.

5) to the right thereby rocking bellcrank104 (Fig. 4) causing a count tobe registered on accept counter 105 (Fig. l).

In this position of the matrix, the matrix being cut as shown, thefeeling bail 74 will also move inwardly, notch 106 therein registeringwith the edge of the matrix. This movement of the bail permits a furtheraction to take place which will be `described more fully hereinafter.

When the matrix, cut as shown, is in the lower position, as shown inFig. 6, iingers'72 and 73 and bail 74 are blocked and prevented frominward movemen In Fig. 6, notch 93 is arranged to cooperate with notch94 in the tinger 72, but might notch 107 instead, in which caseunlocking of the printer bellcrank 97l would occur when the matrix wasin its lower position. Likewise the bail 74 might be permitted to moveto the left when the matrix is in than in its upper position as nowindicated. This might be done by placing the notch 108 in the matrix soas to cooperate with the bail on the side having the notch 106 insteadof the side having the notch 109.

After the dwell 110 in cam 77 has passed, Pull rod 75 is thrust to theright thereby rocking the tie rods 82 and 87 against the lingers ,71,72, 73

and bail 74, freeing these members from the matrix. The matrix thenrecedes under the iniiuence of cam 67. Shortly thereafter cam 55 hasturned suiiiciently to permit arm 50 to move to the right. Carriage 42therefore moves back under the influence of a spring 111 (Fig. 2). thecarriage, a square gages the end of member member in a right handdirection along with the carriage. At approximately the end of its pathof movement, a projection 113, on a member 114 secured to the carriage42, engages a similar projection 115 on a stationary bar 116. Theengagement of these two projections pushes the carriage down therebycausing the square corner 112 of pin 46 to d isengage from member 57,which member is thereupon thrust forward to its initial position byspring 58. Upon the return movement of the carriage, all of the fingers41 strike a. stop and are automatically adjusted to the initial positionready for another testing movement.

After the card 59 has been tested or read, and advanced to the printingpositiomtail 11.7 of bellcrank 97, which rides cam 118. drops intodepression 119 in the cam thereby causing the printing head 98 to forcepaper 120 against emcorner 112 of pin 46 en- 57 and carries the bossedcharacters carried by the slug 59 (Fig. 2).

An inked ribbon or other suitable means (not shown) may be provided inthe usual well known manner to cause a printed record to be made on thepaper. It will be remembered that the lock- Y ing dog 95 was previouslyreleased from the pin of the feeler finger 72 to the shown in Fig. 3.The downward movement of printing head 98 is made very rapid by atension spring 121. The tail 117 of a rubber bumper 122 just before theprinting head forces the paper against slug 59. This bumper issuiliciently resilient to allow the head fully to press the paperagainst 96 by movement right, the position rod 103 (Figs. 4 and bearranged to cooperate with.

its lower position, rather.

Upon return movement of the slug, and thereupon instantly thrusts thebellcrank and head back in a counter-clockwise direction a slightdistance so that the head will be free from the paper, allowing the slug59 to be advanced another step. Further rotation of the shaft 23 causesthe rise 123 in the cam 118 to return the bellcrank 97 to its normalposition. In this position, it is locked by the dog 95 which has beenreturned to locking position by pin 124, which struck the dog during thedownward printing movement of bellcrank-97, thereby flipping the dogback to its locking position. It is maintained locked by spring 9,0engaging'attened face 125 thereof.

The slugs running through the machine may in many cases have embossedthereon certain projections indicating numerical ldata which it may bedesirable to integrate or accumulate from several cards. Theseprojectlonsjjare so positioned on the slugs that movement' of the feelerfingers 41 crossing the slug is dependent on the.

value of the digit indicated. for l, a finger will move but a slightdistancejwhereas for 9 the finger will move 9 times far.

For accumulating or integratingthenumerical data from the slugsactedjfupon.: a series of counters 126, 127 and 128.921e",-iilovided.yThese counters are interconnected groups of pull wires 130, 131,:1132and 133, which are fastened to rocker armsl34 pivoted to thefframe ofthe machine' at 135.l To the other ends of the rocker arms is attached aseries of pull wires 136 which in turnare connected to the ends 137 ofaseries of indicator arms 138, each having a serrated edge 139, with 9teeth spaced at different radial lengths from the pivot shaft l140 ofthe arms. Each of the motion slot 141 in which is`arrang`ed to travelkey 142 attached to the shaft 140. Shaft 140 is rockably mounted and hassecured to one end thereof a crank arm 143 toiwhich is pivotallyconnected a push rod 144. Push rod 144 is supported in operatingposition :by means of a collar 145 mounted on shaft 2 3 and having anelongated opening therein similarly to rods 66 and 75. A cam rider 146is attached to push rod 1.44 and travels on acam 147 (Fig. 7). When. bythe actionof cam 147, push rod 144 is thrust lupwardlythereby rockingshaft'140 in a right handed direction, key 142 engages the right handend of lost motion slot 141 and rotates all of the indicator arms 138 to2. The arms are locked in this position by means of a series of levers148 having catching fingers 149 provided with spring latches 149' whichengagev with locking teeth 150 at the end 137 of the arms. The levers148arepivotally mounted .on a shaft 81 supported by the side'plates 17 and18. These levers are held lockedin retracted position by the feelingbail 741which engages with a projection 152 at the top end of the levers(Figs). y. t

When the bail 74 is permitted to.' move to the left by engagement ofnotch` 106-with the'edge of the matrix, levers 148 are permitted tomoveto the left under ythe intluencefof; vsprings 83 thereby withdrawinglatches 149'1ffrom engagement with teeth 150. Key 141 having previously'been rocked counterclockwise by` the action of rod 144 and itsassociated cam, springs 153 atthe position shown in Fig.`

indicating arms has a lost value indicated by the position of the feelernngers. Rotation of the indicator arms in a counterclockwise directionrocks rocker arms 134 thereby causing an indication to be made on thecorresponding counters, which may be any of 126, 127 and 128.

The edge of matrix 62 engages the edge 154 of the locking levers 148 atcertain points and at these points, even when the feeling bail `74 ispermitted to move to the left, the locking levers cannot move, hence theindicator arms 138 remain locked. In order to permit the indicator armsto move, it is merely necessary to provide suitable notches in the edgeof the matrix. The notches 155 should be placed in alignment with thefeeling fingers 41 engaging with the projection on the slug 59 whichindicates the data it is desired to tabulate. The portion of the edgesleft unnotched would therefore correspond to data not numerical or todata which might be numerical but which itwould not be desired totabulate. It is also possible by proper arrangement of the notches 155to cause each accumulator to register a series of results, each onecontaining a plurality of digits and each of the series separated fromits neighbor by one or more zeros corresponding to inactive indicatorarms. Because of the arrangement of the pull wires 130 to 133 and therocker arms 134, it is possible to interconnect any desired group of.indicator arms 138 with any of the accumulators or parts of theaccumulators 126, 127 and 128. 'I'his feature Ymay be of use where it isdesired to set up on one partof the accumulators one series ofindications andon another part of the accumulators another series ofindications. By this arrangement is is possible to make informationhaving the same characters appear in the same position on theaccumulators of the units regardless of the position which thatinformation occupies on different groups of slugs run through themachine at different periods of operation. Likewise it is possible toarrange. through this interconnecting feature, the data on the differentaccumulators of a unit in vertical columns so that addition orsubtraction may be made as desired.

For counting the total number of slugs passed through the differentunits, a counting arrangement is utilized, comprising a rock shaft 156rotatably supported by the frame of the machine and Carrying at one enda finger 157 which proiects up into the path of movement of the slugs59. As each slug passes to the reading position it encmmters finger 157thereby rotating it and the rock shaft 156. Rotation of the rock shaftis communicated to a counter 158 by means of an arm 159 attached to theshaft and a link 160 connecting the arm with the counter.

In order to prevent the feeling fingers 71, 72,

73 and bail 74 from giving a false indication when' no slug passes tothe reading position, an arm 161 (Fig. 6) is secured to the rock shaft156. This arm is pivotally secured at the end thereof to a U-shapedlocking bar 162 having two legs 163 and 164. Leg 163 has notches 165,166 and 167, which. when the bar 162 is thrust forward by the action ofa slug encountering the nnger 157, registers with feeling fingers 71,72- and 73 thereby permitting them to move toward the edge of thematrix. In like manner leg 164 is provided with notches which registerwith the two sides of the bail 74. When there is no slug in the readingposition, the locking shaft is rotated by spring 168 so that the bar 163is moved backinto locking position. The feeling fingers and bail willthen be prevented from movement towards the edge of the matrix.

The matrix holder arm 63 comprises a plate 168 (Fig. 10) having a pairof guides 169 and 170 for supporting the matrix, which is held thereinby means of spring clips 171, 172 and 173. Intermediate the edges of theguides 169 and 170 is a channel 174 which provides a free spaceunderneath the matrix. For permitting access of the feeding fingers 71,72 and 73 and the bail '74, openings 175, 176 and 177 are furnished.These openings permit the feeling fingers to contact with the edge ofthe matrix without interference. The plate 168 has at one end thereofhinge knuckles 179 which form a part of the pivotal ioint 64.

In order to insure that the proper matrix card will be inserted in theproper unit, a selecting key 180 is utilized. This key nts into a slotin the end of the proper matrix but prevents any matrix not having theproper slot from being fully inserted into the holding arm. Thisselecting key is preferably located at one side of the center line ofthe matrix so that the matrix must necessariiv be .inserted right sideup so that a false reading of the slugs will not occur.

Each time that printing of a slug occurs, the sheet of paper upon whichthe printing record is impressed must necessarily be fed ahead a step.'Ihis is accomplished by means of the paper feed mechanism 181. Thismechanism comprises a pair of friction rolls 182 and 183 of rubber orother material. between which a strip of paper 184 passes. The two rollsare Dressed together rmly enough to insure feeding of the paper uponrotation of the rolls. (Figs. 2, 3, 4 and 9.) The mechanism utilized forrotating the rolls, comprises a gear 185 rotatably mounted on the shaft186, which carries roll 182. Fastened to the gear 185 is an arm 187carrying a spring pressed ratchet pawl 188 which meshes with a toothedratchet wheel 189, keyed to the shaft 186. Secured to the printingbellcrank 97 is a gear sector 190 which meshes with the gear 185. Inoperation, as the tail of the bellcrank 97 descends to cause a printingaction, gear 185 is rotated in a counterclockwise direction as viewed inFig. 3, causing pawl 188 to slip over the teeth of ratchet wheel 189.When the bellcrank 97 is returned to its normal inactive position by cam118, gear 185 is rotated by sector 190, thereby causing pawl 188 toengage ratchet wheel 189 and feed the strip of paper 120 ahead anotherstep for receiving a fresh impression. The paper is fed from the rollsunder a guide bar 191 and thence may be allowed to travel up the face ofthe housing 28, or roll-up on any suitable reel.

The accumulators Each of the accumulators 126, 127 and 128 is preferablyof the differential plural feed type as illustrated, but may be of theordinary kind if dirable. Figs. 13, 14, 15 and 16 show detail views ofone of these accumulators. Each accumulator comprises a main shaft 192and a supporting shaft 193 (Fig. 14). Shaft 193 is fixedly mounted in apair of frames 194 and 195, while shaft 192 is rotatably mountedtherein. On the supporting shaft 193 is rotatably mounted a series ofgear wheels 196, one for each numeral wheel 197. Each gear wheel has aratchet portion 198 with which it engages a pawl 199 (Fig. 2) carried byan arm 200 iournaled on the shaft 193. To this arm is attached one ofthe pull wires 130 or 131. Rotatably mounted on shaft 192 and of adifferential 202.

, 4a flange 206, to which is secured the numeral 222 secured to theappear at wheel 197. Sleeve 205has at its left hand end a small rim 2 07between which and the inner face of the bevel gear 204 is interposed aspring washer 208. This spring washer presses the bevel gear 204 intofrictional engagement with the face of the numeral wheel 197. Flange 206is provided with a gear tooth 209 forming,` with a pinion `gear 210',the usual form of hunting tooth movement or one revolution countingmechanism, such as used in odometers. Likewise journaled on shaft -192and in constant mesh with pinion 210 is a gear 211. "Ihls gear has asleeve 212 which is formed integrally with a bevel gear 213. Gear 213meshes with the-left hand side of the bevel pinions 203 of the numeralwheel of the next higher dimension. The bevel gear 213 of the left hand(as seen in Fig. 14) or zero one of the group of number wheelsnecessarily has. to be keyed to the shaft 192 but all of the othersimilar gears are rotatablyl mounted on said shaft.

Resetting of the accumulator so that all zeros the sight opening isaccomplished by rotating a knob 214 secured to the end of the shaft 192,thereby rotating the shaft, causing a notch 215y therein to engage alatch 216 'slidably positioned in a keyway 217 in thailange 206, andpress into engagement with the shaft by means of a spring 218. Rotationof shaft 192 therefore causes rotation of the alternate number wheels197,v in one direction to a zero position. Rotation of the shaft in theopposite direction causes the alternate series of the number wheels tobe rotated to zero position by engagement of` i a similar latch 219,

facing in the opposite direction to 216, with notch 220 which cooperatestherewith. The two oppositely facing notches and sets of latchesprovided for the two series of alternate position humber wheels arenecessary because successive number wheels rotate in oppositedirections' during the operation of the accumulator. Such rotationoccurs-because of the inherent method of operation of the differentialaccumulator as explained hereinafter. Assurance that the number'wheelswill be set exactly 'at zero is had by the provision of a three fingeredpivotal stop mechanism 221. The three fingered stop 221 is pivotallymounted on an ear frame of the -machine and is adapted to be engaged bya ilnger 223 carried by the shaft 192. As the shaft rection, finger 223engages the middle toe of the stop mechanism thereby moving it until theleft hand .toe thereof contacts with the frame of the machine and stopsfurther rotation of the finger and shaft. stoppage of rotation occurs atthe position A which corresponds to the proper setting of the zeros onone series of number wheels. Ro-

tation of the shaft in the opposite direction causes vthe opposite sideof finger 223 to engage the opposite side'of the middle toe of the stopmechanism, rotating the same until right hand toe en,y

gages the frame of the machine thereby again stopping the finger atposition A, insuring that the zeros of the second set of number wheelswill be properly positioned. An ordinary stationary stopping pin may notbe used at 221 for the reason that. as such a pin would necessarilyMeshing with these spur gears is rotated in one di bev of appreciablewidth, the shaft 192 would not stop in the same position when turnedrighthandedly as it would if turned left-handedly. The zeros on one setof number wheels would therefore be offset with respect to the zeros ofthe other set of knumber wheels.

The operation of the dierential accumulator As the arm 20o is rotated bymovement or me pull wire thereof pawl 199 198thereby causing ring gear201 to be rotated engages ratchet wheel in, for example, acounter-clockwise.direction.l

Bevel gear 213 being held stationary, 203v causebevel gear 204 samedirection, the number wheel 197 being carried along therewith by thefriction created by Athe pinions to be rotated in thel means of springwasher 208. vThe relation of the this unitary movement is transmittedinto like unitary movement of the next higher numeral wheel, but becauseof the reversing action of the "bevel pinions 203, rotation of lthe nexthigher number wheel will be opposite to that of the first number wheel.Because of this reverse rotation numerals of these wheels must run inreverse order on successive wheels, as shown most clearly in Fig. 13.

Should ay number be run in at the same time on two adjacent numberwheels, one of which is necessarily of a different order than the other,carry over from one order to vthe other is entirely unaffected while atthe same time individual indications aremade on both wheels. This willbe clear from a consideration of Fig. 14. Even if bevel gear 213 of theright hand number wheel unit happens to be turning alunit amount becauseof carry over from the left hand numeral wheel unit, the running in ofnumerals directly on the right handnumber wheel by action of the righthand gear wheely 196 will be totally unaffected. The total movement ofthe right hand number wheel 197 will be dependent on two factors, therotation of the bevel gear 213 forming one part of the differential andthe rotation of the ring gear 201 forming another part of thedifferential, these rotations will be in their proper directions tocreate an additive movement of the right hand number wheel.

From this description it will be seen that the advantage of thedifferential accumulator in connection with our `tabulating listingmachine is that counting may be started from any number wheel at all andnot necessarily from one number wheel having a fixed and invariableorder with respect to the other wheels. Hence it is possible to set upon a single accumulator a plu- Rotationof the gear 211 rality Vofdifferent tabulations having numbers by a suitable cover 225 which maybe slid back and forth whenever necessary. The hand buttons 214 forresetting the accumulators are made accessible by another opening 226 inthe housing.

After the slugs have traveled through the variousI tabulating andprinting units they pass to the magazine units, of which any number maybe of the sorting type such as unit of Fig. 1 which is illustrated inmore detail in Fig. 20.

This unit is provided with reading fingers and a matrix similarly to theprinting and tabulating units already described. As these portions vofthe mechanism operate in the same manner in the sorting unit they arenot shown in detail in Fig. 20. In the figure 300 indicates a bellcrankpivotally supported at 301 and having at 302 a presser foot which ispivotally mounted but held centered by a spring 303. The other arm 304of the bellcrank is identical with arm 117 of the printing bellcrankalready described, and cooperates with a similar operating mechanism.This mechanism comprises a cam 305 carried by shaft 23, with which thearm is held in engagement by means of a tension spring 306. The shaft 23also carries a cam 307 which is positioned beside cam 305 and serves tooperate a set of feeler fingers. A third cam 308 is positioned on theshaft and cooperates with an arm 309 connected to a matrix holder 310which carries a matrix 311 properly positioned with respect to indicatorfingers 312 of the feeler fingers. All of this mechanism just describedwill be recognized as similar to that of the units previously explained.

The arm 300 is Vprovided with a locking pawl or dog 313 pivotallysupported at 314 and having a holding spring 315 which is arranged topress against either of two at faces 316, 317. 'I'his pawl is furnishedwith a latch projection 318 which is adaptedto engage with a pin 319 onthe arm 300 and thereby hold the arm in retracted position. For trippingthe pawl and releasing arm 300 a drag link 320 having a lost motionconnection 321 with the pawl is provided. This link connects at itsother end with a bellcrank 322 rockably supported at 323 and having oneend pivotally joined to the matrix holder 310 through a link 324. Inoperation, when the matrix holder is permitted to rise under theinfluence of spring 325, due to the holes in the matrix fitting thepattern of the finger 312, bellcrank 322 is rotated left handedly,thereby moving pawl 313 to the right out oi' engagement with the pin319. Upon subsequent rotation of the cam 305 the tail 304 of arm 300enters the dwell in the cam thereby rocking bellcrank 300 to the rightand forcing presser foot 302 against the slug 326. Pressure on the slugbends resilient clips 327,

' forming the bottom of the trackway at that point,

downwardly, far enough entirely to free the slug therefrom. The freedslug is pressed down into the magazine 328 where it engages on otherslugs and thrusts them down slightly against a frictionally heldsupporting member 329 resting on a spring 330. Any other suitablemagazine may of course be used.

The locking pawl 313 is reset by a pin 331 on the arm 304 in the samemanner as the printing arm locking pawl.

In order to permit the slugs to be pressed downwardly into the magazine328 the conveyor 8 is made just long enough to move an individual sluginto position over the magazine opening. If the slug is not pressed downinto the magazine it will be slid ahead in the trackway by the next slugpushed ahead by the conveyor. In this man ner slugs rejected by unit 5will move to unit 6.

Field of use Since the machine is a combination listing and tabulatingmachine, it is in general adaptable to all those problems for whichlisting and/or tabulating machines are used. Because it performs thefunctions of both types of machines it is particularly adaptable toproblems for which neither is wholly suited.

As a simple illustration, addressing machines are used for preparinglists for pay rolls. This machine will do this and in addition total theindividual salaries to give the total monies required. This can be doneon only one unit each week for weekly paid employees. At the end of eachmonth two units could be used, one for the weekly employees and one forthe monthly, and at one running both pay rolls could be made out.

'Ihe machine may, for another example, be used for printing the names ofvarious employees having certain characteristics, and totalling theirsalaries as well if desired. In case it is desired to print the names ofemployees to which certain characteristics apply, and at the same timelist the salaries of all of them having been employed in the company tenyears, this may be done at one unit while at a subsequent unit in themachine the salaries of the entire group of employees, regardless of theperiod of their employment, may be tabulated, and all their namesprinted. If it is necessary to obtain any other information concerningthis particular group, or to obtain a list of names of those out of thegroup of a particular nationality, color, or degree of education, thismay be done at still another unit. As all of the units act on the slugsduring one passage through the assembled machine, the time necessary forsecuring several different kinds of information is substantially nolonger than the time required to obtain a single lot of information.The'uses of the machine are not limited to personnel and salaries,however, as it is applicable as well to other matters such as sales,inventories, and all kinds of business records.

The slugs run through the machine may be sorted by the receivingmagazine units, those having a particular group of characteristics beingplaced in one magazine and those of the other characteristics beingplaced in another magazine. This feature may for example be used insorting out the address plates or slugs or those persons whosesubscriptions to publications have expired, or in inventory work,to'segregate the items which should be replenished at once, or withinsome given time.

The following table will indicate to a certain extent a kind of recordwhich may be kept by the slugs. This particular table is made out in thefield of personnel records rather than merchandise, sales, inventory orother records. Of course it will be understood that the various main anddetail characteristics positions may be used to indicate any desiredkind of data and that the personnel information contained in this tableis merely for purpose of illustration. In the table the group of maincharacteristics corresponds to the vertical rows of projections on theslugs while the detail characteristics indicate the location of theprojection in th row.

The operation of the machine is as follows: Suppose it is desirable toprint the names of all weekly salaried married persons of the male sexhaving more.than two dependents and earning between $40.00 and $90.00 aweek, with the fur- -ther requirement that the person be white, a

citizen by birth, naturalization or marriage, and have a four-yearAmerican college education, Suppose also that no account is to be takenoi the age, nationality, year employed or religion. The matrix is madeup as shown in Fig. 18, the cross hatched places being cut out. Thismatrix is inserted in the holder 168 so that notch 227 of the matrixcoincides with the key of the matrix holder. It will be remembered thatthe position of the notch 227 determines the number of the unit inwhichthe matrix is to be positioned and in this case the matrix may benotched to indicate unit number 1.

ber by the friction ot the trackway 37; At position 39, during thereturn movement of the pushing pawls, the carriage 42 carrying thereading fingers or feelers 41, is thrust forward as a result of themoving of lever arm 50 to the left. This movement is caused by cam 5,5carried by shaft 23, which is also driven by the motor 10. As thefeelers move to the left, pin 46 is forced downwardly by the action ofcam surface 56, thereby thrusting the '-Ieeling fingers down below thelevel of the top of the projections carried by the slugs 59. The feelershaving been thrust down towards the face of the slug, during theiradvance movement engage with the projections on the slug and are therebystopped at diierent positions depending on the locations of the projec-DETAIL CHARACTERISTIC Group Poe.

For

. example, with a slug as indicated in Flg.'19, the

foiu'th feeler .ringer from the lett will be stopped atlposition 8indicating that John Doe of Bradford, New Jersey, identiiication #501,is married. The other angers will stop in various positions. indicatingthat John Doe is on a weekly salary,

l male sex, has nve dependents, was born in 1878,

has a four-year college education, in U. 8.1A., was born in the U. S'.A. and has no other nationality, is a Protestant, has made slow ad--vancement, waaemployed in 1910, is a citiaen by birth, white, and drawsa salary ot $055.33.

The carriage 42 now having been advanced and all of the feeling fingersstopped in their proper locations, cam 67 reaches a position permittingpush rod 66 to be drawn upwardly by its tension spring, thereby rotatingthe matrix holder arm 63 in a counter-clockwise direction thrust thematrix 62 towards the indicator fingers 65 carried by the feeler fingers41. Assuming the matrix 62 to be the one shown in Fig. 18 we see thateach of the fingers 65 will be positioned so as to enter one of theholes in the matrix indicated by the cross hatched portions. The slug ofJohn Doe is therefore accepted and the matrix arm and matrix take theposition shown in Fig. 3 of the drawings. Cam 67 having acted to raisethe matrix holding arm towards the indicating finger 65, cam 77 has nowreached such a. position that cam rider 76 of push rod 75 has droppedinto dwell 110 thereby permitting the push rod and arms 80 to move tothe left under the influence of springs 83. This causes tie-rod 82 tomove to the left thereby permitting bail 74 and levers 148 to move tothe left. Movement of the bail 74 towards the matrix is permitted bynotch 230 therein. Had the matrix not been accepted, the bail could nothave moved to the left.

Those levers 148 corresponding to group characteristics 20 to 24inclusive move freely into the notch 228 thereby withdrawing catchingfingers 149 from locking teeth 150 of the indicator arms 138. I'he otherlevers 148 are blocked by striking the unnotched edge of the matrix 62and prevented from moving to the left far enough to unlatch the catchingfingers. The indicator arms 138 which are unlatched, are immediatelyrotated in a counter-clockwise direction by their springs 153 at a speedcontrolled by the counter-clockwise rotation of shaft 140 until one ofthe teeth of each serrated edge 139 engages the rear end of thecorresponding feeler ilnger 41. The rotation of each indicator arm willtherefore be dependent on the position of the end oi' the feeler arm,which in turn is dependent on the position of the projection on the slugwith which the feeling finger has been engaged. The movement of theindicator arms therefore corresponds to the numerical value of theposition of the feeler fingers, and the pull wires 138 are moved to acorresponding distance. The movement of the wires, through the action ofrocker arm 134, causes a proper numerical indication to be made by theone of the accumulators 126, 127 or 128 to which the indicator arms areconnected. This may be for example, accumulator 128, in which case theaccumulator, having been previously set to zero, will now read 5533, theamount shown on the slug as the salary of John Doe.

Subsequent to the setting of the indicator arms, shaft 140 carrying key142, which has been in a left hand position with respect to the lostmotion slot 141 in the arms 138, is rocked in a right hand direction toreset the indicator arms. 'I'his is brought about by rotation of the cam147 to such a position that cam rider 146 and push rod 144 are thrustupwardly thereby swinging arm 143 secured to shaft 140, in a right handdirection. As the indicator arms 138 are moved to their originalposition spring catches 149' of fingers 149 reengage the locking teeth150 holding tle indicator arms in place for another operation.

Left hand movement of arms will rotate rocker arms 84 in a clockwisedirection thereby withdrawing tie-rod 87 from engagement with feelerfingers 71. 72 and 73. These feeling fingers then move into engagementwith the edge of the matrix. Finger 72 moves into the notch 231 in theedge of the matrix. This movement causes locking dog to be released frompin 96, through the agency of drag link 94, and rotated to a right handunlocked position where it is held by the action of spring 99 engagingwith flattened face 100 of the dog. At the same time finger 73 movestowards the matrix, notch 102 engaging with the edge thereof, causing anindication to be set up on the accepted counter 158, through the actionof the pull rod 103. The arms 80 remain to the left and levers 148remain engaged in notch 228 during the whole time of counter-clockwiserotation of indicator arms 138 and are reset prior to their clockwiserestoration. Prior to the restoration, the pull rod 75 was thrust to theright by action of its cam 77 thereby throwing the levers 148 andfeeling fingers 71, 72 and 73 back to normal position.

At the instant when the carriage 42 had been moved to its extreme lefthand position by the lever arm 50, pin 46 moved beyond the end of member57 thereby permitting the carriage to rise vertically a sunlcientdistance to allow the feeler fingers 4l to clear the top of theprojections of the slugs. Upon movement of rod 75 to the left and theactuation of the tabulating mechanism and printing lock, furtherrotation of the driving motor 10 causes the slugs to be stepped forwardto another position. Continued rotation of the shaft 23 causes thedepression 191 to come under the tail 117 of bellcrank 97 and thebellcrank is thereupon rotated rapidly in a clockwise direction underthe influence of spring 121 bringing the printing head 98 down so as topress the paper against the upper side of the slug or typewriter ribbonpositioned there over, to cause printing. The upper side of the slug, aswe will see by Fig. 17, carries certain information in raised letters ortype so as to be printed in a readable manner on the paper. In the caseof the slug shown-in Fig. 19 the printed matter is John Doe Foulton Kan.#501 At the instant when the printing head 98 is about to contact withthe paper 120, the tail 117 of the bellcrank 97 strikes rubber bumper122, deformation of which causes the bellcrank to rebound, therebythrowing the printing head free from the paper and permitting freemovement of the slugs. Upon the printing movement of the bellcrank 97.gear of the paper feed mechanism was rotated counter-clockwise by gearsector thereby causing the ratchet pawl 188 to slip over the teeth ofratchet wheel 189. Return movement of the bellcrank 97 therefore causesa reverse motion of pawl 188 which thereupon turns ratchet wheel 189 andthe paper feed rollers, so that the paper is fed ahead another position.

Further rotation of the shaft 23 brings the rise 123 of the cam 118 intoengagement with the tail 117 of the bellcrank 97 thereby restoring it toits normal position, as indicated in Fig. 2. At the end of the printingstroke of bellcrank 97 tail 117 thereof struck the locking dog 95sufllciently to move it against the action of spring 99, to the left, sothat flattened face 125 engages with the flat face of the spring,thereby holding the dog in such position that upon return movement ofbellcrank 97 to locking position, pin 96 is moved into locking positionwith respect to the dog 95.

Subsequently to the resetting of bellcrank 97 cam rider 54 of lever 50moves into the depression of cam 55 thereby permitting the lever 50 tomove in a right hand direction under the influence of its spring. Thismovement carries the carriage 42 to the right thrusting the rear ends ofthe feeling fingers 41 against the hubs of indicator arms 138 whichserve as stops thereby holding the fingers in a fixed position duringthe remaining portion of the movement of the carriage. Upon completionof the movement of lever 50, the fingers 41 will be fully reset and theentire mechanism ready for another cycle of operation. As the carriage42 travels to the right on its resetting movement, projection 113 ofmember 114 carried thereby engages with projection 115 carried by theframe of the machine thereby causing the carriage to be depressedslightly. This depression of the carriage permits the member 57, whichwas being carried in a right .hand direction against spring 58 bythrusting movement of square corner 112 of pin 46, to snap baclr` to theleft hand position shown in Figs. 2 and 3.

After the slugs have been fed through the various units 2, 3 and 4 ofthe machine, wherein they may be acted upon in a similar fashion as inthe unit just described, but for the purpose of obtaining differentinfomation, .they move to a unit 5. At this unit the slugs may beseparated into two groups. Those of one group are forced down into themagazine 328 of the unit while the rest are fed forward to unit 6 andare there thrust down into magazine 9 by the action of pusher plate 14which is oscillated at the proper instant of time by shaftA 16 coupledto shaft 23 and forming a continuation thereof.

'I'he selecting action of unit 5 is determined by a matrix 311 carriedthereby.v A set of feeler fingers,- not shown, similar to those of thetabulating units described moveat the proper time, into engagement withthe projections on the slug, whereupon matrix holder 310 rises testingindiacting fingers 312 with matrix 311. If the pattern of the fingersfits the matrix the latter will rise, thereby moving pawl 313 to theright, through the agency of link 324 bellcrank 322 and drag link 320.This action unlocks the bellcrank 300 which, after the next step ofconveyor 8, is permitted by its controlling cam 305, to rotate clockwisefashion and force the presser plate 302 against the slug 326thereunder.' By this action the slug is thrust out of its trackway,springing out of its path resilient fingers 327, and into the magazine328. Clockwise movement of the bellcrank 300 causes pin 332 to strikepawl 313 and snap it back to its normal holding position, similarly topawl 95, so that upon the following restoring movement of the bellcrankthe pawl engages with pin 319 and is locked thereby.

Slugs that are not accepted by unit 5 are pushed ahead steprby step byfollowing slugs until they arrive under presser foot 14 which thruststhem into magazine 9. v v

' No tabulating mechanism has been shown but this might obviously beused in exactly the same manner as in units 2, 3 and 4. Likewise unit 5might be provided with testing ngers for controlling tabulation just asin the units above described. .The bellcrank 300 might also becontrolled in the same manner as the printing bellcrank 97, of thoseunits.

The slug shown in Fig. 19 serves merely to illustrate a particular slugthat might be accepted by the matrix 16. But it will be understood thatmany vother slugs differing from that shown in Fig. 19 may be acceptedas well. For example, regardless of the location of the projection ofthe slug in group characteristic position 7, 8, 11, 12, 13, 14, 16, 11,22, 23 or 24 the slug may be accepted depending on the position of theprojections representing the other characteristics. Also the matrixaccepts slugs regardless of the location of the projection in position21 between detail position 4 to 8 inclusive. Similarly it accepts slugswith projection in either 0, 1 or 4 detail position of general position18 and in general position 5 the projection may be anywhere from 3 to 9and the slug still be accepted, etc. Each of the twentyfour positions ofthe matrix must be provided with one or more perforations regardless ofwhether information is desired of that point or not. If no informationis desired all ten detail positions will be perforated. There must beone projection only in each of the twenty-four positions of each slug.For example the twentieth position of John Does card reads 0 which meansthat his salary is less than $100.00 per week.

By reference to the chart given above it will be seen that where onecommon group of detail characteristics occupies more than one rowcorresponding to group characteristics it is necessary to place on anyslug or matrix a projector indicating that the true reading is not inthat column but in the other. 'For example, if Joe Doe was an Italiandetail position 0 of group characteristic 11 would have a projectionindicating that the nationality of Joe Doe was not to be found underthat group characteristic. Detail position 1 of Igroup characteristic 12would have a projection sition 1 and-group position 2, detail position'(7 This arrangement isi means monthly sales. useful in certaincircumstances where a particular class of information would ordinarilytake up two or more group positions as more information can beconcentrated in a small space. No indication is needed that theinfomation is "not of the following", that is, not in that groupcharacteristic. A

'I'he operation of a single unit has been explained in detail whenutilizing a matrix such as shown in Fig. 18. The other units of themachine may be provided with matrices different from that shown in Fig.18. The matrix shown in Fig. 18 may be utilized for determining theaverage salary of alimen-answering the conditions thereon perforatedmerely by dividing the total indication of counter 158 into that ofcounearning $50 a week and having the other characteristics enumeratedby the matrix.
